Watch all three tutorials to quickly get 800 Renown. You can also skip the cinematics of the tutorials and still get the Renown. This allows you to get 800 Renown in approximately 15 seconds. You can also get another 200 Renown for going to Uplay (may need to install an app) and selecting the "Rewards" option. You can spend 40 Uplay points to get 200 Renown. You can then use the 1,000 Renown to unlock two operators immediately at the start of the game.

Easy "Coming Through!" achievement

While playing on the "Consulate" map in Casual/Ranked Multiplayer or Terrorist Hunt and you are attacking, simply place a breach charge on one of the windows of the building and go through it to get the "Coming Through!" achievement.

Easy "Death From Above" achievement

While playing on the "House" map in Casual/Ranked Multiplayer or Terrorist Hunt and you are attacking, go to the back of the house. Use your grapple hook to reach the roof, then go to the master bedroom window on the right with the yellow "XX" on the window. Break the window and enter the room. Go to the back of the bedroom and look for a square tile with metal around it on the floor. Use a breach charge on it to get the "Death From Above" achievement.

Easy "Fortress" achievement

While playing on the "Bank" map in Casual/Ranked Multiplayer or Terrorist Hunt and you are on defense, use an operator to put up two reinforcements on breakable walls (soft walls that can be breached) to get the "Fortress" achievement.

Easy "Oh Yeah!" achievement

While playing in Casual/Ranked Multiplayer with a Thermite operator and you are attacking, use Thermite on a reinforced wall, which is a wall with spikes on it. You can also use it on the other side (blue) of the reinforced wall if you breach the enemy base. However, if you place the Thermite on a reinforced wall with electrical shocks emitting from it, you will take damage and your Thermite will be destroyed. You can see if the wall is charged by scanning for electronics or touching it and seeing if you take damage. The Thermite will also not work if the enemy team has a signal disruptor next to the reinforced wall.
